Abstract
The invention relates to the field of compound fertilizer, and particularly relates to a bioactive slow-release compound fertilizer for promoting growth. The fertilizer is prepared from the following raw materials in parts by weight: 10-15 parts of a 1250-2000 mesh diatomite, 13-15 parts of potassium chloride, 18-20 parts of ammonium nitrate, 15-18 parts of diammonium hydrogen phosphate, 20-22 parts of urea, 12-14 parts of a calcium magnesium phosphate fertilizer, 2-3 parts of ammonium molybdate, 15-16 parts of enoki mushroom dregs, 2-4 parts of grapefruit peel, 1-3 parts of a broussonetia kazinoki leaf powder, 4-6 parts of 1-hydroxy ethylidene-1,1-diphosphonic acid, 10-12 parts of sheep manure, 6-8 parts of a cottonseed hull powder, 10-12 parts of polyvinyl alcohol, 3-5 parts of tributyl phosphate, 1-2 parts of sodium polyphosphate, 1-2 parts of nano silica, 1-2 parts of linalool, 1-3 parts of Chinese honeylocust spine, 2-4 parts of zinc gluconate, 6-8 parts of table vinegar, and 4-5 parts of an auxiliary agent. The compound fertilizer is wide in raw material sources, improves a phenomenon of single and fixed traditional compound fertilizer nutrients, and allows double coating to be formed on the nutrients by utilizing diatomite and a coating agent in the process, so that the nutrients in soil are not easy to lose, the fertilizer efficiency is more durable, bioactive components in the raw materials can promote crop growth effectively, and obvious effects of increasing yield and income are reached.
Description
technical field [0001] The invention relates to the field of compound fertilizers, in particular to a growth-promoting bioactive slow-release compound fertilizer. Background technique [0002] In modern agricultural production, compound fertilizer can be seen everywhere. It has the advantages of high nutrient content, less auxiliary components, high fertilizer utilization rate, and convenient storage and application. It plays an important role in promoting high and stable crop yields. Slow-release compound fertilizer is an important category of compound fertilizers, and it is also the focus of research on the development of my country's chemical fertilizer industry. Its slow-release principle is to coat a thin layer of hydrophobic substances on the surface of fertilizer particles, so that the internal nutrients are slowly released to the In the soil, nutrients are continuously supplied to crops, which effectively improves the utilization rate of fertilizers. However, the exi...
